Ansonmei sat on the top of the car CMOS image sensor, with sales exceeding 150 million

[Introduction] Ansonmei holds the top spot in the automotive CMOS image sensor supply market with 46% market share. Omnivision, Toshiba, Sony, Jingtai and Melexis are among the top. In the ADAS market, Ansonmei has a market share of 70%. %, so far more than 150 million automotive CMOS image sensors have been shipped.

As new-generation cars increasingly focus on the development and application of active safety systems, such as 360-degree panoramic viewing systems, lane departure warning systems, rear-view cameras, active cruise control, driver sleepiness warning systems, reversing visual systems, passenger monitoring Blind spot monitoring, parking assist systems, rear-end collision warning, automatic parking systems, and market demand for automotive-grade CMOS image sensors are increasing year by year.

Yi Jihui, vice president of business development at ON Semiconductor, said: "Active safety and autonomous driving are the future development trend of automotive electronics. By 2020, each luxury car will contain up to 20 cameras."

Currently in this supply market, Ansonmei is the top spot in the automotive CMOS image sensor supply market with 46% market share, followed by Omnivision, Toshiba, Sony, Jingtai and Melexis. In the recently booming automotive ADAS market, ON Semiconductor has a market share of 70%, far ahead of other suppliers. To date, ON Semiconductor has shipped more than 150 million automotive CMOS image sensors, producing 10 unique automotive-grade CMOS image sensor products.

Yi Jimei, Vice President of Business Development of Anson China, said: “Ansonmei is the world's first supplier of automotive-specific CMOS image sensors and the world's first supplier of CMOS image sensors to meet ASIL (Automotive Safety Integrity) requirements. The CAGR of the automotive CMOS image sensor market is much higher than 28%."

Anson has been developing automotive CMOS image sensors for more than 10 years and has successfully developed many competitive innovations and algorithms, such as LFM technology (which can reduce LED flicker) and stacked wafer technology (this can Improve pixel performance and reduce power consumption), global shutter technology (for best energy efficiency in its class), 300mm advanced manufacturing technology and BSI back-illuminated technology (which improves pixel sensitivity in low illumination environments), complete image processing and perspective Correction algorithm, ON Semiconductor is also the first CMOS image sensor supplier in the industry to meet ASIL (Automotive Safety Integrity Level) requirements. ASIL is a key requirement for automotive autopilot systems.
